Halo

Building web apps andinternal business systems

I'm a software engineer who builds web applications and internal business systems, from backend APIs to admin dashboards. I'm currently the founding Software Engineer at MidHub, a heavy-equipment marketplace, while studying Computer Science (Software Engineering) at BINUS University.

At MidHub I develop the marketplace backend with NestJS, from real-time chat and payments to search, and lead sprint planning as acting Product Manager. Before that I built ERP and accounting backends, internal tools and the ARKATO Group company website with its admin panel, plus a confidential internal platform for PT Rajawali Octorys Sundari.

I'm always happy to connect with fellow engineers and people building business software.
